摘要/Abstract

摘要： 为了解决恶臭污染问题，采用接种辫硫杆菌ZG11的生物滴滤塔A与接种活性污泥的生物滴滤塔B对硫化氢气体进行了4个多月的脱臭实验研究，主要考察了进气浓度、冲击负荷和氮利用率对硫化氢去除率的影响以及实验前后压力损失的变化。结果表明：当硫化氢进气浓度低于600 mg/m3，即进气负荷Nv低于113.33 g/(m3?h)时，滴滤塔A的去除率接近100%。当进气浓度低于750 mg/m3，即Nv低于133.33 g/(m3?h)时，滴滤塔B的去除率接近100%。当进气流量为8 m3/h时，滴滤塔A与B的压力损失分别为176.4 Pa/m和313.6 Pa/m。与滴滤塔A相比，滴滤塔B启动快，去除速率高，抗冲击负荷能力强，但压力损失大，受氮源的影响较大。

Abstract: The deodorization experiment of hydrogen sulfide（H2S）was carried out continuously using bio-trickling filter A inoculating sulfur-oxidizing bacteria and bio-trickling filter B inoculating activated sludge in order to solve the odor pollution. The two bioreactors were operated for more than four months to investigate the effects of inlet concentration，shock loading and consuming quantity of nitrogen on the removal efficiency of H2S. Pressure drops of the bio-trickling filters were also compared before and after the experiment. The results suggested that removal efficiency of the bio-trickling filter A was nearly 100% when inlet concentration of H2S was lower than 600 mg/m3 and the corresponding inlet loading was lower than 113.33 g/(m3?h). Removal efficiency of the bio-trickling filter B was nearly 100% when inlet concentration of H2S was lower than 750 mg/m3 and the corresponding inlet loading was lower than 133.33 g/(m3?h). Pressure drops of the bio-trickling filter A and B were respectively 176.4 Pa/m and 313.6 Pa/m at 8 m3/h of gas flow rate. Compared with bio-trickling filter A，the bio-trickling filter B performed a relatively rapid startup，relatively high removal efficiency and ability to resist shock-loading. However，the bio-trickling filter B had a relatively high pressure drop and its removal efficiency was easily influenced by nitrogen source.
